UNITED STATES PATENT OFFICE.

E. THARP, OF CINCINNATI, OHIO.

WASHING-MACHINE.

Speccation of Letters Patent No. 20,101, dated April 27, 1858.

To all whom it may concern:

Be it known that I, EDMUND THARI, of Cincinnati, Hamilton county, Ohio,have in vented a new and useful Improvement in lVasliing-Machines; and Ihereby declare the following to be a full and exact description of thesame, reference being had to the accompanying drawing, making part ofthis specification.

My invention consists in the combination of a trough of quarterspherical form with a vertical rotating disk, by means of which agyratory motion is imparted to the materials to be washed and all partsare successively subjected to compression and rubbing.

In the accompanying drawings Figure l1 is a perspective view from thefront of the machine. Fig. 2 is a vertical axial section.

A frame or base A supports a cylindrical box or drum B, of very shortaxis in comparison to its diameter and having its heads in a verticalposition. This drum is closed on all sides excepting a semicircularopening at the lower portion of one of its heads, fitted to whichopening is a quarter spherical trough or half bowl C.

D, is a vertical disk journaled concentrically within and nearly fillingthe drum B. The face of the disk D, next the trough O, is armed withsuitable protuberances such as ribs ol, and brushes e. In the presentillustration the shaft F, of the disk D extends forward over the troughO, and is pro vided with a crank Gr by means of which the disk isrotated.

I-I, is a discharge cock for drawing off the water.

The operation is as follows: The trough O, being supplied to about halfits height with water and articles to be washed the operator applyingone hand to the crank G, rotates the disk D, causing the protuberancesthereon to act on the adjacent portions of the clothing and while sodoing to impart a slow gyratory or vortical motion to the contents,chieiy in a horizontal direction, so as to constantly present differentparts to the action of the disk. It is also found that the describedconstruction and action of the disk and trough operate to compresssuccessive portions of the clothes into the bottom of the trough andtemporarily expel the water from their interstices after the manner ofpulling. For some description of clothing the unemployed hand may beused with advantage in occasionally manipulating the contents so as toexpedite the operation on parts which most require it, an action whichis rendered extremely easy by the form, presentation and position of thetrough O, relatively to the operator. The waterprojected by thecentrifugal action of the disk, is caught and returned by the drum B.

In large establishments the disk may be rotated by power and severalmachines may be operated by a single attendant.

I claim as new and of my invention here- The arrangement and combinationsubstantially as set forth of the vertical rotating disk D, and quarterspherical trough O, for the purpose explained.

In testimony of which invention I hereunto set my hand.

EDMUND THARP.
